How to Play PropelX
The goal is to clear as many zones as possible, then collect before the plane crashes. Every zone cleared adds a multiplier to the running total; a crash forfeits the whole round. The steps below cover a full round.
-
Set your bet value
Bets run from 0.10 to 1,000. Use the "+" and "-" buttons to move the value incrementally, or open the bet menu and pick a size from the list.
-
Press BET to wager
There is a five-second window between rounds to commit a bet. The BET button changes to BET ACCEPTED once the wager is placed.
-
Watch the climb
The countdown finishes and the jet begins climbing. The BET button turns yellow and reads COLLECT. Above the jet the route is marked with three kinds of danger zone:
- Cloud - the safest to pass, awards the smallest multipliers.
- Lightning - a moderate chance of destroying the plane, awards mid-sized multipliers.
- Skull-marked fighter - the hardest to survive, awards the largest multipliers.
Passing a zone adds a multiplier to the running total. The multiplier shows on the chart and the COLLECT button shows what that total is currently worth. The counter starts at ×1.00.
-
Collect or climb on
Once at least one zone is behind you, you choose between two options:
- Climb on - risk the running total against the next zone for a larger multiplier.
- Collect - the round ends immediately and the total is credited to your balance.
Zones are visible above the jet before it reaches them, so the decision can be made against what is coming. A large total with a fighter approaching is a very different position to a small total under a run of clouds.
Game Features
- Three danger zones
- Clouds, lightning and a skull-marked fighter each carry their own risk and their own multiplier size. All are visible above the jet before it arrives, so the risk on the next stretch is known rather than guessed.
- Multipliers accumulate
- The win is a sum of everything passed so far rather than one number climbing, and it is wiped in full by a crash.
- Dual bet panel
- Two independent bets can run on the same round, each with its own stake and its own collect point.
- Live rounds
- Rounds play out on SmartSoft's servers with every player on the same flight, rather than one round per player.
- Recent results ticker
- A live feed down the left side lists recent rounds, including the provably fair hash for each.
- Auto play
- Runs a set number of rounds unattended, collecting automatically once the running total hits a target you nominate.
- Bet history
- Past rounds are listed with the multiplier, bet value, win amount and timestamp.
- Live leaderboards
- Daily, weekly and monthly rankings against other players.
As the jet climbs through three danger zones: clouds, lightning, and a skull-marked fighter, the win multiplier skyrockets. The goal is simple: hit Collect before the plane randomly explodes. Wait too long, and your bet is gone.

PropelX FAQ
What is PropelX?
PropelX is a crash game from SmartSoft Gaming where a jet climbs through a route split into danger zones. Passing a zone adds a multiplier to a running total, and the zones come as clouds, lightning or a skull-marked fighter that pay accordingly. Any zone can crash the plane, which loses the round. Collecting at any point secures the total built up so far.
Can I play PropelX for free?
Yes. The demo uses play money and needs no registration or download, running at the same 97% RTP and ×1,000,000 ceiling as the real-money game.
What is the difference between the danger zones?
Clouds are passed most often and pay the least. The skull-marked fighter pays the most and destroys the plane most often. Lightning sits between them. Because each zone is visible before the jet arrives, you can decide whether to collect or climb on based on what is coming rather than on chance alone.
Can I place two bets on one round?
Yes. The dual bet panel runs two bets at once on the same flight, with separate stakes and separate collect points, so one can be taken early while the other rides further.
